The VehicleDynamics Library (VDL) is a tool for modeling, simulation and analysis of the dynamics of vehicle motion. Handling behavior is the primary target, but the library is also well-suited for studies of other vehicle properties. Compared to other tools, VDL is easy to get started with and yet features versatile multi-domain modeling, fast simulation, and exible analysis of both full vehicles and relevant subsystems. In this article Modelon AB and Volvo Car Corporation present joint work using the VehicleDynamic Library to evaluate future actuator constellations in combination with a validated model of a Volvo XC 90 vehicle. This paper has examined viable vehicle actuators and the use of them to maintain stability in safety critical driving situations. The study, which has been jointly performed by Modelon and Volvo Car Corporation, has been carried out by developing a vehicle model in Dymola/VDL and a vehicle controller in Simulink. To guarantee a low level of model uncertainties, the vehicle model passed a validation process based on measurements of subsystems and the complete vehicle respectively. The vehicle model was successfully validated without any tuning of parameters obtained from subsystem tests. The vehicle model was equipped with a number of different actuators, which were controlled to assist the driver through a double lane change manoeuvre. The results reveal that the overactuated vehicles have considerable capability to maintain stability.
